Electron diffraction tube
Article No: 06721-02
The electron diffraction tube enables the demonstration of the wave nature of electrons by observing interference patterns that become visible on the fluorescent screen after passing through a polycrystalline graphite lattice.The electron wavelengths can be determined as a function of the anode voltage using the diffraction rings and the lattice plane spacings of graphite, thereby experimentally confirming de Broglie’s hypothesis. Highly evacuated tube for precise and reproducible experiments Direct observation of Debye–Scherrer diffraction on the fluorescent screen Precise control of the high voltage using a compatible power supply (06721-04) Technical Specification Heater voltage: 6.3 V AC Max. anode voltage: 5000 V Anode current: approx. 0.1 mA at 4000 V Graphite lattice constants: d₁₀ = 0.213 nm, d₁₁ = 0.123 nm
